For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or connected through an intermediate medium, or the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0030] Such asFigure 1 As shown, the concrete pouring machine for road construction in this embodiment includes a base 10, a fixed bracket 20, a mixing drum 30, a mixing paddle 40, a driving motor 50, a leveling mechanism 60, a rolling mechanism 70, a power supply 80 and an electric control box 90.

[0031] A running wheel 100 is provided at the bottom of the base 10, and the running wheel 100 can be a self-locking universal wheel. A handrail 110 is also provided on one side of the base 10. The handrail 110 can be used to push the base 10 and the structure above it to move, thereby facilitating the pouring of concrete.

[0032] The fixing bracket 20 is disposed on the base 10 , the mixing drum 30 is disposed on the base 10 in the longitudinal direction and connected to the fixing bracket 20 , the power supply 80 and the electric control box 90 are disposed on one side of the mixing drum 30 and are disposed on the base 10 through the fixing bracket 20 .

[0033] A feed port 31 is provided on one side of the mixing drum 30, and the feed port 31 is tiltedly arranged on the side wall of the mixing drum 30 in a manner of being higher outside and lower inside to facilitate feeding; a discharge port 32 is provided at the bottom of the mixing drum 30, and a distribution row 33 is provided at the bottom of the discharge port 32, and an electric control valve 34 is provided between the discharge port 32 and the distribution row 33.

[0034] Among them, the driving motor 50 can adopt a 12V or 24V DC motor, the power supply 80 can adopt a 12V or 24V DC mobile power supply, and the electrical control box 90 is a conventional technical means in this field, which can control the start and stop of the driving motor 50 and the switch of the electric control valve 34. The power supply 80, the electrical control box 90, the driving motor 50 and the electric control valve 34 are connected by electrical signals.

[0035] The leveling mechanism 60 is disposed at the bottom of the base 10 and between the front and rear running wheels 100 . The rolling mechanism 70 is disposed at the bottom of the base 10 and between the leveling mechanism 60 and the rear running wheel 100 .

[0036] like Figure 2 As shown, the stirring paddle 40 is longitudinally arranged in the mixing drum 30, and the driving motor 50 is arranged on the top of the mixing drum 30 and is in driving connection with the stirring paddle 40; wherein the mixing drum 30 is a tapered cylinder structure that is wide at the top and narrow at the bottom, and the stirring paddle 40 is a tapered auger structure that is wide at the top and narrow at the bottom. The driving motor 50 drives the stirring paddle 40 to rotate, which can prevent the concrete from solidifying or settling, and can also push the concrete material to the side of the discharge port 32 under the action of the auger structure.

[0037] like Figure 3As shown, the fabric row 33 is a flat triangular through-groove structure. Since the diameter of the discharge port 32 is relatively thick and the thickness of the through-groove is small, the material pressure in the discharge port 32 is relatively high. The concrete material coming out of the discharge port 32 can spread to both sides of the fabric row 33 under the action of pressure and be evenly discharged along the fabric row 33.

[0038] As Figure 4 shown, the leveling mechanism 60 includes a telescopic rod 61 and a leveling plate 62. The upper end of the telescopic rod 61 is connected to the bottom of the base 10, and the lower end is connected to the leveling plate 62.

[0039] The telescopic rod 61 includes a sleeve 611, a movable rod 612, and a spring 613. One end of the movable rod 612 is slidably disposed in the sleeve 611. The spring 613 is disposed in the sleeve 611 and its two ends are respectively abutted against the inner top wall of the sleeve 613 and the top of the movable rod 612. A limiting ring 614 is provided at the bottom opening of the sleeve 611, and a limiting block 615 is provided at the top of the movable rod 612. The movable rod 612 is restricted inside the sleeve 611 through the cooperation of the limiting ring 614 and the limiting block 615.

[0040] As Figure 5 shown, the leveling plate 62 is a corrugated plate structure, which is more conducive to evenly spreading the concrete.

[0041] As Figure 6 shown, the rolling mechanism 70 includes a first connecting rod 71 and a roller shaft 72. The upper end of the first connecting rod 71 is rotatably connected to the base 10 through a hinge seat 73, and the lower end is rotatably connected to both ends of the roller shaft 72. A scraping blade 74 is also inclinedly provided on the front side of the roller shaft 72. Both sides of the scraping blade 74 are connected to the first connecting rod 71 through second connecting rods 75.

[0042] The roller shaft 72 presses on the concrete by its own weight to further roll the leveled concrete, so that the concrete becomes more flat. The scraping blade 74 can scrape off the concrete adhering to the surface of the roller shaft 72 and slide down along the scraping blade 74 to the front side of the roller shaft 72, so as to be rolled again, avoiding waste of concrete.

[0043] The utility model performs scraping and rolling treatment on the discharged concrete through the leveling mechanism 60 and the rolling mechanism 70, so that it is evenly and flatly spread on the road surface, eliminating the trouble of subsequent manual leveling, which is beneficial to reducing the construction cost and improving the construction efficiency.

[0044] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement; when the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.
